Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] Such as Figure 1~3 As shown, based on the RFID double warehouse rail transport vehicle, it includes a vehicle frame 1 and a guide wheel 6 located at the bottom of the vehicle frame 1. There are 4 guide wheels 6, which are symmetrically installed around the bottom of the vehicle frame 1. The guide wheels 6 are formed by It consists of a large-diameter main wheel and two coaxial small-diameter wing wheels symmetrically fixed on both sides of the large-diameter main wheel, and is fixedly connected with the corresponding drive shaft through a key.

[0034] The frame 1 is a "mountain"-shaped frame structure, with two end convex frames and a middle convex frame, the end convex frame set at th...

Abstract

The invention discloses an RFID (radio frequency identification)-based two-bin rail-bound conveying vehicle and a rail layout and positioning control method and belongs to the technical field of automatic control. The RFID-based two-bin rail-bound conveying vehicle comprises a vehicle frame, a driving device, a guide wheel, a power supply system, a control device, RFID sensors and a positioning sensor, a front storage bin and a rear storage bin are arranged on the vehicle frame, the control device is connected with the power supply system, the RFID sensors and the positioning sensor respectively and controls running of the guide wheel through the driving device, the RFID sensors are mounted at two ends of the bottom of the vehicle frame and can recognize RFID labels used for marking storage cells, and the positioning sensor is mounted at the center of the bottom of the vehicle frame and can recognize positioning points on the front side and the rear side of each RFID label. The front storage bin and the rear storage bin of the rail-bound conveying vehicle are enabled to align at the storage cells respectively to complete multiple-variety and small-batch cargo conveying, storing and fetching, so that operating flexibility of the rail-bound conveying vehicle is enhanced.

Description

technical field [0001] The invention relates to an RFID-based double-cabin rail transport vehicle and a track layout and positioning control method, belonging to the technical field of automatic control. Background technique [0002] The traditional warehousing system uses manual access to goods, and the forklift driver drives the forklift into the shelf lane. Due to the narrow space of the lane, it is difficult for the forklift to drive flexibly in it. In order to reduce the possibility of the forklift colliding with the guide rail, a single shelf is not allowed to be too long. These deficiencies seriously restrict the access efficiency of goods and the space utilization rate of warehouses. [0003] The roadway stacker is often used in the automatic storage system, which is a kind of crane that shuttles back and forth in the narrow roadway of the high-rise shelf to perform access operations. The goods are taken out and transported to the entrance of the roadway. The heig...
